Not such a swell idea
Serena Williams withdrew from her opening match at the Hopman Cup because of inflammation in her left knee, an early setback in preparations for her Australian Open title defence. No. 1-ranked Williams practiced Monday ahead of her scheduled season-opener against Elina Svitolina of Ukraine in the international mixed-team competition at Perth Arena, but withdrew from the match and was replaced by Vicky Duval. Duval lost 6-4, 6-1 to Svitolina and Alexandr Dolgopolov beat Jack Sock 6-4, 6-2 to clinch the best-of-three Group A match for Ukraine before the U.S. pair won the mixed doubles 6-2, 6-3. Williams said she was confident she’d be able to join Sock in the U.S. team to play the Australia Gold team on Tuesday.
